Abstract
A kind of safety anti-releasing staight shank spanner fixator.Mainly solve the problems, such as that time-consuming and laborious, spanner easily slips and makes to operate unsafe when the big gland of existing 250 gate of high pressure and oil pumping machine crank axis nut dismounting.It is characterized by: being vertically welded with two pieces of junction steel plates symmetrical above and below (2) on center screwed pipe (1) outer wall, junction steel plate (2) end is connected with top plate (3), and top plate (3) is parallel with center screwed pipe (1) axis.The safety anti-releasing staight shank spanner fixator can guarantee that spanner will not slip, safe operation.
Description
Technical field
The present invention relates to machinery field, specifically a kind of safety anti-releasing staight shank spanner fixator.
Background technique
250 high pressure gates are using a kind of most, the higher gate of spoilage on oil field shaft mouth, first in gate maintenance process
First need to dismantle on the big gland of gate, could each component in inside to gate repair.The shell of gate by big gland with
Pedestal two parts are threadedly coupled, and are usually covered outer six side on big gland using six side's spanners in dedicated staight shank, are utilized sledgehammer
Special spanner rotation is struck, gland and pedestal are separated.Since gate weight, close, the screw corrosion that are threadedly coupled get rusty
Seriously, outer outer six side increased on gland is very shallow, and insecure with six side's spanners set in staight shank, when sledgehammer strikes, staight shank is least
Greatly, interior six sides spanner is easy to slip, and easily flies out and hurts sb.'s feelings.
Meanwhile the fixture nut of oil pumping machine crank axis there is a problem of same in disassembly, spanner can not securely entangle spiral shell
Mother, spanner easily slips when causing to dismantle nut.
Summary of the invention
Time-consuming and laborious, spanner when in order to overcome the big gland of existing 250 gate of high pressure and oil pumping machine crank axis nut dismounting
It easily slips and makes to operate unsafe deficiency, the present invention provides a kind of safety anti-releasing staight shank spanner fixator, and the safety anti-releasing is straight
Handle spanner fixator can guarantee that spanner will not slip, safe operation.
The technical scheme is that a kind of safety anti-releasing staight shank spanner fixator, including center screwed pipe, the center
Be vertically welded with two pieces of junction steel plates symmetrical above and below in screw thread pipe outer wall, junction steel plate end is connected with top plate, and top plate with
Center screwed pipe axis is parallel.
It is connected between the top plate and junction steel plate by top plate lacing wire.
The center screwed pipe is internally connected with screw rod, and the end of screw rod is connected with baffle.
The invention has the following beneficial effects: due to taking above scheme, which is connected to by center screwed pipe
On 250 gate threaded rods or oil pumping machine crank axis, allen wrench is withstood by baffle, in this way in the disassembly big pressure of 250 gates
Lid or when oil pumping machine crank axis nut, can slip to avoid spanner, and spanner is not in rebound phenomena, make to operate it is safer, greatly
It is big to improve disassembly success rate.

Fig. 1 is main view of the invention；
Fig. 2 is left view of the invention；
Fig. 3 is schematic diagram when dismantling the big gland of 250 gates；
Fig. 4 is schematic diagram when dismantling oil pumping machine crank axis nut.
The center 1- screwed pipe in figure, 2- junction steel plate, 3- top plate, 4- top plate lacing wire, 5- screw rod, 6- baffle, 7- bolt, 8-
250 gate threaded rods, the big gland of 9-, 10- crank axle fixture nut, 11- allen wrench, the centre 12- axle sleeve, 13- crank axle,
14- crank.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings:
As shown in Fig. 1 to Fig. 4, a kind of safety anti-releasing staight shank spanner fixator, including center screwed pipe, the center screw thread
1 outer wall of pipe is welded with two pieces of junction steel plates 2 symmetrical above and below, and junction steel plate 2 is rectangle, and 1 outer wall vertical of center screwed pipe,
Two 2 ends of junction steel plate are connected separately with top plate 3, and two top plates 3 are rectangle steel plate, flat with 1 axis of center screwed pipe
Row.It is connected between the top plate 3 and junction steel plate 2 by top plate lacing wire 4, plays reinforcement effect.
Screw rod 5 can also be connected with inside the center screwed pipe 1, the end of screw rod 5 is fixed with baffle 6, takes out in disassembly
When oil machine crank axle nut, screw rod 5 is connected on center screwed pipe 1.
The safety anti-releasing staight shank spanner fixator can be used for dismantling the big gland of 250 gates, can be used for disassembly oil pumping
Machine crank axle nut and some other part for needing straight spanner to dismantle.In the big gland of 250 gates of disassembly, by screw rod
By removing on center screwed pipe 1, screw rod 5 and baffle 6 are not used.By 11 sets of allen wrench on the big gland 9 of gate, center spiral shell
Line pipe 1 is connected on 250 gate threaded rods 8, rotates the fixator, and top plate 3 is made to withstand on 11 side of allen wrench, by interior six side
Spanner 11 is held out against on big gland 9.Then allen wrench 11 is rotated, the big gland 9 of gate can be removed.Since spanner is consolidated
Determine device to hold out against, it can be to avoid its slippage.
When dismantling oil pumping machine crank axis nut, screw rod 5 is connected on center screwed pipe 1, baffle 6 is connected by bolt 7
It connects in 13 end of crank axle, by 11 sets of allen wrench on crank axle nut, the first tight intermediate axle sleeve in 11 left side of allen wrench
12 and crank 14；It is rotated further by fixator, top plate 3 is made to withstand on 11 right side of allen wrench；Then allen wrench 11 is rotated
Crank nut is removed.
